Description
In June 2021, NKT completed a repair operation on the Kontiskan‑1 high-voltage direct current interconnector between Denmark and Sweden. Under this project NKT located the fault, carried out civil works and physical repair of the damaged power cable, and performed Time Domain Reflectometry (TDR) measurements after the repair, followed by dissection and analysis of the affected cable section. This work restored the reliability and availability of the subsea HVDC link and formed part of NKT’s broader maintenance and repair activities for Nordic transmission system operators.
